vtion .to an oil bath thatthe lowerl partjof the structure rotates inthe oil bath. VThus Certain amount rofoiljis picked up and this oil tends to .move outwardly, r ap idly, under thejinfluence ofcentrifugalforce. The fins are intended tointerceptthis outwardly Inov-v 'ingu oil and byr their contigurationldirect g-it into. the ports, ^11. It will beobserved that theportsfthemselvesvmay be .inclined .out- V wardly,E so that the tendencyljof the oil'to moveoutwardly will`cause' it-to travel to i kthe left inv Fig. 5 or toward `'the workin face 9a. of wear plate`9. l

In the modified form ofthe inventionV illustrated'l in Figs. 7 and 8,we place fins or lwebs 12 about the periphery of the wear plate, it being notedr that these fins are not continuous, but as indicatedfat 13, lie in' yspacedrelation to eachother. so that'oil may freely enter the space in the rear of the wear plate. Theoil .picked isA thrown outwardly by centrifugal force and since the presence of the vwebs or fins 12 prevents the free escape of the oil, acertain slight presthese webs which'y causesthe Voil to' travel face of the wear plate. Thev building upof pressure as described isbr-ought about the fact that when the wearplateof Figs., 7 and 8 is vsecured to the Vabutment 8 in place kof the wear plate 9, the webs 12 constitutev a closure about the outeredge of the space, that is formed between the wearplate and the abutment The means for holding the.r wear'plate in spaced relation tothe abut-4 ment forms no partof the present invention but is included in our priorv application above referredto 5 Like thewear plate ofour prior application the wearplate of the'p'resent invention may bemade in twosemi-circular parts, which facilitates the placing'of the parts in position without thefnecess'ity'ofy remov-V 'ing theishaft 5'from its bearing.v .100

1. AIn combination a horizontalsha'fti'and la thrust bearing forthe same,'con1prising` 119,11. A

sriY i an abutment carried" by the shaft and rotating therewith, a vertical Wear plate Vspaced from said abutment but connected thereto and rotating therewith and having ports formed therethrough from the rearl to the front face thereof and this carried by said plate at the mouths of the respective portsv projecting outwardly beyond the vertical face of the plate tov thereby direct oil moving' under theinfluencerof centrifugal ,force into said ports, to cause said oil to travel laterally through the Wear plate.

Y 2. A structure as recited in claim 1 Where-V in said ports are inclinedy outwardly.

.3. The combination with a horizontal shaft and a vhorizontal bearing vfor thexsame, of an abutment carried by and rotating with the shaft and` lying in spaced relation thereto, a vertically disposed Wearv plate secured to and rotating with theabutment and having its Working face disposed toward and thrusting against an end of said rhorizontal bearing, vmean-Safor holdingthe vertical wear plate in'sp-aced relation to the abutment, ports passing laterally through the Wear yplate from the Working face thereofto 'said space and ins carried by said Wear plate at the mouths of the respective ports and projecting outwardly beyond l the vertical rear face of the Wear plate, .to thereby direct oil moving under the influence of centrifugal force, into saidports,` toy Y cause said oilto travel laterally through the *y
